My homemade keyboard has Cherry keys (well... Chinese Cherry, I ripped out the keys from the cheapest keyboard I could find ) but I haven't figured out how to "professionally" print the keycaps. I just glued bits of paper on top of the keys. It looks sad now. I have 2 Ti99's I could sacrifice but I'm not going to do it till I figure out how to silk-screen keys or something...
Even if the germans only make nice keycaps and not a full keyboard that will probably sell well at a decent price (with a extra keycap for delete or rubout option).
